Question

The mass m = 14.7 kg shown in the figure is displaced a distance x
= 0.139 m to the right from its equilibrium position. k1 = 115 N/m
and k2 = 203 N/m.
m is between k1 and k2

a) What is the net force acting on the mass (enter first) and what
is the effective spring constant?
b) What will the frequency of the oscillation be when the mass is
released?
c) What is the total energy of the mass-spring system after the
mass is released?
